T all whom it wwq concern:

Be it known that L'Jorm WEST, a subject of the King of Great Britain.and Ireland.

whose residence and pos't' oflice address is Barfield House, WestDidsbury,',;near Manchester, in the county of Lane aster ..England, haveinvented cert-am new and useful Improvements in Machines for Chargingand Drawing Gas-Retorts; and I do hereby declare the following to be afull, clear, and exzact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention relates to improvements in apparatus for charging anddrawing gas-retort-si. e.,for charging the retorts with coal anddrawing. the coke product therefrom after the coal has been carbonized.

The object of my invention is the production of a self-propelled machinein which the operations of charging and drawing are accomplished bymechanismoperable by one set of gearing.

A further object is to so position the oper atinghmersof said ma'ichinethat they are accessible to the operator at all" times without changinghis position.

Other objects are the provisionof charging and'drawing mechanism adaptedtd he raised or lowered at will to operate in retorts p0si tionedatdifl'erent heights and to? provide hoisting mechanism to accomplishthis object; to provide novel mefln's for tilting and manipulating thedrawing mechanism at will; so that it can be made to pass over the cokewhen entering the retort and lowered to engage and. draw the coke, andto provide improved mechanism for operating the charging and drawingdevices and novel means for automaticallytilting the charging-scoop.

To accomplish these objects, my invention consists in the novelconstruction and ar-' rangementof parts hereinafter more specific allydescribed, reference being had to the accompanying drawings, in whichFigures 1 and 2 are opposite views of the combined charging and drawingmachine. Figs. 3 and 4 are respectively a front elevation and plan viewof the same adapted for carrying a double-scoop charger. Fig. 5 is aside view of a modified form of combined charging and drawing machineadapted for carrying a singles'scoop charger. Fig. 6' is afifoilgfelevation of tge same.

erring sai drawings, lady to, Figs; 1, 2, 3, andti', the apparatus andparticucomprises the upright frames a a a a and b b ,b b, which aresecured in any suitable manner to the truck 1 of the machine. which ismounted on wheels 2 and is adapted to be propelled on ways or rails 3along the bench' of retorts i by means of a motor 5.\vhich may be drivenby steam, compressed air. or electrical energy. the said motor beingpro-.' vided with suitable reversing mechanism or gear to admit of itsbeing operated in. either direction. The said motor is. provided with adriving-shaft 6, on which is mounted a worm (not shown) whichcommunicates motion through a worm-wheel 8 to the vertically-disposedshaft 9, on which said wormwheel 8 is mounted, the said shaft beingsupported in bearings 9', which are secured to the upright a of themachine. The said shaft 9 is provided with or has mounted thereonclutches 10 and 11, which are operated by means of the lever 12, thelower end of which is connected to one end of the connecting-rod 13, theopposite end of which rod is connected to the counterweighted lever 14,which is connected to and actuates said clutch 10. A vertically-disposedconmeeting-rod is connected at the lower end to one of the members ofsaid lever 14 and at the upper'end to the lever 16, which is connectedwith and actuates clutch 11. When lever 12 is in the sition shown in 1and 2, clutch 10 is thrown into engagement with clutch 17 which isintegrally connected with the bevel-wheel 18, which l m' llydoose onshaft 9, thereby rigidly through the worm-gear, heretofore described,and said wheel 18 to the bevelwheel 19, j mounted on' the. axle 20 ofthe machine in mesh therewith,'for ,t he urpose of ropelling the machinealong the ench 0 retorts.

shown in Fig. 6. The hoisting-cable e of the rake-bar fra ne iswound onsaid chaindrum e and led over pulleys e" e" to the rake-frame a, towhich itis attached at e, as shown in 6. When the hoisting-gear is putinto motion, the chains 0 0, and e?- simultaneously raise of'lower thehopper 74', the. charger-scoop 45,. and the rake-bar 86,

heretofore described. The movements of the piston a of said cylinder arecontrolled by the. hand-lever e through the connections a e,-e., e, ande". he' said piston is attached to or connected with the rack e,

which mesheswith and operates apinione,

which is mounted on the end of shaft 6, on which is also mounted thechain-drum e", overwhich the chains 0 and e" pass. The

over, respectively, ulleys 0 and c mount-. ed in the rake-bar rame, thesaid chains being for the purpose of driving the rake into said chainspass from said drum onto and and withdrawing the same from the retorts.

The rake is pivoted and rocks therein by the lever and the rod 0 asheretofore de- 'scrizedu- The charger is driven into and.

withdrawn froni the retorts by means of the motor 0 which comprises thecylinder c, in which the piston e is adapted to operate; The said pistonis connected with, a rash 0",.

which engages and transmits power to a PlIllOIl e on the shaft e for thepurpose of operating the chain-drum e, mounted on said shaft. The saidpiston carries the.

cross-head e, on which a tappet e secured! The said piston in itsmovements causes the said tappet to contact with the tap et-lever a,which is'pivotally connected wit and adaptedto actuate theverticallydisposed rod 6', (shown'indotted lines in Fig. 5,) whichoperates the valverod e" for the purpose of controlling the admission ofmotive fluid through the valve-casing e to the cylinder at eachbackward-and-forward movement of the said piston. Chains (not Sl10'I1)pass over the chain-drum e and are attached to the ends, respectively,of the purpose of advancing the same into and mthdrawin'git fromtheretorts. The vessel c'-is for thepurpose-of containing water when theapparatus is 'act uated by hydraulic pressure, and the rods in dottedlines in Fig.5 show a valve-actuating mechanism to' control theadmission of water from said vessel to the motor 0- 'As it does notrelatedirectl'y to the present'invention, I
